Ischemia can be caused by the occlusion of the arterial supply or venous drainage for a particular tissue.
A localized area of necrosis caused by an interruption of the blood supply is an infarction. For instance, a myocardial infarction is a localized area of necrosis in the heart muscle. An MI is commonly known as a heart attack.
Ischemia=decreased oxygen/nutrients Infarction=no blood flow to the area ischemia can leads to infarction. ischemia means, reduced of blood supply to specific organ. while, infarction refers to death tissue.
Infarction, which means cell necrosis.
Infarction is death of body tissue (also known as necrosis) due to insufficient blood or oxygen supply. Ischemia is a related term relating to the decrease in oxygen or blood supply. Gangrene is the condition resulting from bacterial invasion of an area of necrosis.
Apoptosis is cell death via shrinkage, whereas oncotic necrosis is cell death via swelling. The term necrosis was used for cell death before these two different processes (shrinkage and swelling) were discovered. For this reason, it is still sometimes used to refer to both apoptosis and oncotic necrosis. However, necrosis is also sometimes used to mean only cell death via swelling. To avoid confusion, it is best to use the terms apoptosis and oncotic necrosis (and not just 'necrosis').
Liquefactive necrosis is good for your body, especially your brain (due to the beneficial liquids produced) but coagulative necrosis is bad due to the clumping and coagulation (i.e. clotting) that occurs.Coagulation necrosis is the "acute" necrosis in which the protein fibers become denatured and everything turns into a semi-solid mess of dead tissue. Liquefactive necrosis is a more "chronic" necrosis in which the dead tissue is digested into a liquid which can then be removed by the macrophages.
necrosis is death of cells with underlying/ or death of cells that cause inflammation. necrosis has to have an underlying injury. ischemia is decreased blood supply to tissues/ cells due to obstruction/ constriction of vasculature - indeed, this is an injury, and can lead to necrosis of cells if not resolved quickly! Note that apoptosis is programmed cell death - i.e. nucleus control is involved, and there is no inflammation - it is clean cell death! this is awesome.
A heart attack (myocardial infarction) is the result of a blockage in an artery which feeds the heart, so the heart becomes starved for oxygen.
InfarctionAn infarction is an area of tissue death caused by ischemia.it is called an infarct.
DefinitionSplenic infarction is death of tissue ( necrosis) in the spleen due to a blockage in blood flow.Causes, incidence, and risk factorsCommon causes of splenic infarction include blood clots, infections such as endocarditis, and blood diseases such as sickle cell anemia.
Necroses is the plural of necrosis
The term for tissue death is either necrosis or apoptosis, depending on the situation. Apoptosis is preprogrammed tissue death, while necrosis is not preprogrammed. An infarct is an area of tissue that has died due to lack of blood supply.
